Abstract:
Nasopharyngeal carcinoma (NPC) is caused by Epstein-Barr virus (EBV) infection, yet incorporating measurement of EBV DNA levels into clinical practice remains a challenge. Here, we summarize the relationship between NPC and EBV infection before describing the use of cell-free DNA as a plasma biomarker in cancer. We then compare conventional polymerase chain reaction methods and emerging next-generation sequencing approaches for EBV viral load detection emphasizing their prognostic and predictive utility. We conclude by considering how assay standardization, novel molecular approaches, and alternative clinical specimens may be leveraged to bring EBV testing into the routine care of patients with NPC.
